They say you can't judge a book by its cover, but that's not true; you shouldn't judge a book by its cover. You can, and chances are you do it all the time, so better make sure that cover is good, right?

They also say a picture's worth a thousand words, and that's where graphic design comes in.

How you do that is a little bit of a tougher question, and one that this episode of PBS Off Book dives right into. So take a minute to learn about and come to appreciate that silent, subtle signals you see surrounding you every day. There's a lot to appreciate when you look in the right places. [PBS Off Book]
